The need is to update, add or delete a lot of items at once (for example, the selected items). Sample of batch editing: https://demos.telerik.com/kendo-ui/grid/editing.
Perhaps this may become possible through methods on the grid that invoke the CUD operations.

ADMIN EDIT
There is a sample project that accomplishes most of these goals: https://github.com/telerik/blazor-ui/tree/master/grid/batch-editing
The grid state offers a great deal of flexibility in terms of controlling the grid, up to putting it in edit/insert mode.
